Highcharts stacked column chart is missing some values? - highcharts

Question

in the picture below the middle column is missing the yellow portion. if you look at the label column you can see a value of 10 for green, 12 for yellows(missing) and 5 for reds.
I have checked the json and the database records they look fine and match to these values but highcharts is just not rendering these sections.
this happens randomly across the whole chart.
var chartOptions = dashboards.getChartOptions(data.ChartSize,
{
title: { text: options.title },
series: options.series,
legend: $.extend({
enabled: (data.legend) && data.legend != 'none',
align: align,
verticalAlign: vAlign,
layout: layout,
y: 20
}, legendOptions),
tooltip: {
formatter: function () {
if (this.series.chart.options.plotOptions.series.stacking && !data.isTimeCharted) {
return '<b>' + dashboards.Utils.shorten(this.series.name, 20) + '</b><br/>'
+ dashboards.Utils.shorten(this.point.category, 20) + ': ' + this.y;
}
else if (data.isTimeCharted) {
return '<b>' + dashboards.formatDate(this.point.category) + '</b><br/>'
+ (data.ChartType === 'line' | data.ChartType === 'column' ? '<b>' + dashboards.Utils.shorten(this.series.name, 20) + '</b><br/>' : '') +
(percentage ? parseFloat(this.percentage).toFixed(2) + '%' : this.y);
}
else {
return '<b>' + dashboards.Utils.shorten(this.point.category, 20) + '</b><br/>'
+ (data.ChartType === 'line' ? '<b>' + dashboards.Utils.shorten(this.series.name, 20) + '</b><br/>' : '')+
(percentage ? parseFloat(this.percentage).toFixed(2) + '%' : this.y);
}
},
followPointer: (data.ChartType!=="line"),
shared: false
},
chart: {
type: data.ChartType,
renderTo: chartContainer[0]
},
xAxis: {
type: (data.isTimeCharted ? "datetime" : "categories"),
categories: (data.isTimeCharted ? undefined : currentData.chartData.categories),
minTickInterval: (data.isTimeCharted ? 24 * 3600 * 1000 : undefined),
labels: (data.isTimeCharted ? { formatter: null } : (data.ChartType === 'column' && (data.topXvalue >=20 || data.topXvalue == 0)) ? { rotation: -85, align: 'right' } : undefined)
},
yAxis: options.yAxis,
plotOptions: {
series: {
stacking: data.stacking,
}
},
exporting: {
enabled: false
}
});

Answer 1

Some things to check:
Is that your data for each series sorted correctly by date (category)?
Check that each series has an entry for every date.
